Hi, Im having installed & configured Exchange 2010 in Virtual Server with AD in separate Virtual machine. All exchange roles are there in 01 server itself. Issue is: when accessing owa on http it asks for user name & password, if entered it gets redirected to https. When accessing OWA from IIS via browse its getting redirected without any UID/Paswd to HTTPS In IIS under default site 1. HTTP is redirected to https://owa.mydomain.com/owa 2. SSL is OFF 3. Basic AUth. enabled rest are disabled In OWA Virtual Directory 1. Redirection is off 2. SSL is OFF 3. basic auth enabled. Under autdiscover\ECP\EWS\Active Sync\OAB SSL is enabled
